LRUCache has Concurrency problem

[looly]

Current behavior

Hello, I found the class: LRUCache

use LinkedHashMap and use read lock for get, but the LinkedHashMap get method is not thread safe, the element will move to last of queue when get it.

True! the thing is that the cache utilities were not migrated to the https://github.com/oblac/jodd-util.

I am under impression that there are better cache libraries out there... not sure if we should maintain this one anymore?

[looly]

U means that cache will be removed next time?

[igr]

It already is :) If you take a look in the https://github.com/oblac/jodd-util there is no cache anymore...

But I am open for discussion!

[igr]

So, wdyt @looly ? Would such a small cache make sense?

[looly]

Un.... not sense.

I mean if some user use the old version jodd-all will be touch off the bug，and its very difficut to find out it.
